ABSTRACT

Final and other layers of road structures and their corresponding elements significantly affect the generation of heat islands in areas in which they are located Air temperature increases in relation to the surrounding areas during the formation of heat islands. This paper presents the results of field research which measured the temperature of all elements of two road underpasses, which are integral parts of the D7 (E73) state road in the city of Osijek, the Republic of Croatia. The tests were conducted from April to November 2014. The aim of the performed tests was to determine the effects of solar radiation on the temperature of constituent elements of road underpasses. The measurements were performed with the aim of determining the dependence of location of individual elements of the construction in space and material properties of which the same are made. The obtained test results indicate that the temperatures of the observed elements of the road underpasses significantly vary depending on the position within the construction, surface albedo and external weather conditions.

摘要

道路结构的最终层和其他层以及它们的相应元素会极大地影响其所在区域中热岛的生成。在形成热岛时，空气温度相对于周围区域升高。本文介绍了现场研究的结果，该结果测量了两条道路地下通道的所有元件的温度，这是克罗地亚共和国奥西耶克市D7（E73）国道的组成部分。测试于2014年4月至2014年11月进行。测试的目的是确定太阳辐射对道路地下通道构成元素温度的影响。进行测量的目的是确定结构中各个元素的位置在空间上的依赖性以及所制造的材料的属性。获得的测试结果表明，所观察到的道路地下通道的温度会根据建筑物内的位置，地表反照率和外部天气条件而显着变化。
